Wifi enabled controller Weather Underground

I know that this is late but the Hunter Hydrawise Wifi controller uses Weather Underground for their weather data. Their basic free plan lets you choose from local airport weather stations. I believe that they allow you to choose your own weather station that is connected to Weather Underground. The settings for predictive watering include wind, humidity, temperature, previous rainfall and predicted rainfall. We have installed a bunch of these and are happy with them. I did a comparison chart of the timers on my site here is a link to it. Wifi Controller Comparison
